ATLANTA (AP) -- The Atlanta Hawks doubled their victory total from last season.
For perspective on that accomplishment, if they again double their win total next season, they'll match Miami's 52 wins this season. The Hawks then would have the same luxury as the Heat of resting starters in the final week of the regular season to prepare for the playoffs.
Tyronn Lue's 3-pointer with 8.3 seconds left gave the Hawks a 103-100 victory Tuesday night over a Miami team that was without its head coach and rested its three top players.
Miami, looking ahead to the playoffs and intent on having its top players avoid injury, stayed close despite having leading scorers Shaquille O'Neal and Dwyane Wade watch the game in street clothes. Coach Pat Riley was visiting his sick mother in upstate New York.
"I thought we gave ourselves a chance to win; we didnt quite get it done," said Miami assistant coach Ron Rothstein, who filled in for Riley.
"But I think we accomplished what we wanted to tonight in terms of minutes and getting guys time on the floor and trying to get ready for this weekend. Hopefully we came out of it healthy. I think we did."
The Heat listed O'Neal, Wade and Gary Payton as inactive, taking three starters who average 55 points out of the game.
"We have a lot of guys who can play on this team," Haslem said. "Just because they don't start doesn't mean they can't play. Everybody on this team on any given night is capable of producing, whether it be on the offensive or defensive end."
The Hawks have improved from 13 wins last year to 26 this season, still only one game out of last place in the Southeast Division. The Hawks close their season at Cleveland on Wednesday night.
Rothstein, who spoke with Riley earlier in the day, said he didn't know if Riley would return for Miami's final regular-season game Wednesday at Boston.
Wright, who scored a career-high 19 points, hit two free throws with 1:56 left to pull Miami within one point of the Hawks at 98-97.
Lue's jumper gave Atlanta a 100-97 lead, but Earl Barron answered to again cut the lead to one point.
With 37 seconds left, Simien tied the game with a free throw.
Lue missed a 3-pointer, but Zaza Pachulia grabbed the rebound for Atlanta, creating another opportunity for Lue, who sank a 3-pointer from the top of the key with 8.3 seconds left.
Wright missed a last-second shot for Miami.
"Going out with a win at home is the best thing," said Lue, who had 15 points.
Jason Kapono had 16 and Walker added 14 for Miami.
Wright, a second-year player who was averaging only 1.1 points, hit three 3-pointers and had seven rebounds and four assists.
"He had his jumper going," Rothstein said. "He fell in love with the 3 a little bit. Dorell is a young kid that's just finding his way. He's got a world of athleticism. I'm really pleased with what he did tonight."
Wright, a 6-foot-8 forward, spent time at point guard late in the game.
"He made some mistakes playing out of position in crunch time and things like that, but there was no lack of effort," Rothstein said. "Live and learn. That's what tonight was really about, more than anything else."
Wright and Miami's other backups seized the rare opportunity to play lead roles. The Heat managed a 28-all tie at the end of the first quarter and then pulled away with a 19-3 run early in the second period. Jason Williams, who had 13 points in the first half, and Wright hit 3-pointers in the run.
Miami led 49-37 at the end of the run, but Atlanta answered with 10 straight points, including 3-pointers from Joe Johnson and Josh Childress, to trail 53-52 at halftime.
Following a 78-all tie at the end of three quarters, the Hawks took the lead with a 12-4 run to open the fourth quarter.
